Title: Log-handling device
IPC: A01G23/00
Filed: 1969-04-12
Abstract: A tree harvesting structure 15 is supported on a tractor frame 10 and comprises a base 16 supporting a boom 17 controlled by an hydraulic cylinder 18. A second boom 19 is carried by the boom 17 and is controlled by an hydraulic cylinder 20. At the free end of the boom 19 is a loggripping device 21, below which is a logshearing device 22. The devices 21, 22 may be angularly controlled by an hydraulic cylinder 23. A log-gripping and pulling device comprises a U-shaped structure 27, bolted at 26 to axle 24, that includes a bight portion 28 fixed to a crash plate 31 and a pair of rearwardly extending and diverging arms 29, 30. Supported on the arms 29, 30 on respective, substantially vertical, pivot pins 37, 38 are extension arms 40, 41 biased to an open position, Fig. 1, by torsion springs 46. A cable 57 passes from a winch 25 through openings at the ends of the arms 40, 41 to an anchoring eyelet 68. When the cable 57 is slack the arms 40, 41 are open with the cable 57 extending loosely between them, Fig. 1. For gripping and pulling a log 70, the log 70 is placed on the cable 57 and the slack taken in by the winch 25. This tends to draw the arms 40, 41 in substantially horizontally as the cable 57 tightens due to the weight of the log 70. Normally there is sufficient friction between the cable 57 and the log 70 so that the log 70 is pulled forward as the arms 40, 41 close until it abuts the crash plate 31. In the transport position, Fig. 3, the cable 57 is drawn tightly around the log 70.

Patent ES-409185-A1 (ES)
Title: Redundant fraunhofer recording system
IPC: G03F7/12
Filed: 1972-12-01
Abstract: When a pinhole array is employed as a redundancy means in recording a redundant Fraunhofer hologram, such as a holographically prerecorded motion picture, a moving noise is normally present in the reconstructed image when the hologram is moved during playback. The effect of this moving noise is eliminated by situating the hologram recording medium at or in the immediate vicinity of the image plane of the pinhole array during the recording of the hologram. By recording the hologram in this manner, flicker-type noise is also improved.

An alarm is actuated when the count stored in the difference accumulator reaches a value equal to that of an adjustable digital alarm set.
Patent ES-449328-A1 (ES)
Title: Digital testing and power control in a digital communication system
IPC: H04M1/253
Filed: 1976-06-28
Abstract: The invention is concerned with digital communication systems and there is disclosed a digital telephone system wherein any digital telephone may be switched, by control from a local exchange, between a power-up state wherein continuous operating power is consumed by the telephone and a power-down state wherein the telephone is effectively turned off except for the consumption of a small amount of power sufficient only to enable communication between the telephone and the exchange. A telephone is powered-up by detecting, at the telephone, a control signal in the digital data transmitted from the exchange to the telephone. Each telephone includes a detection circuit for detecting the control signal and actuating a power rationing switch to switch the telephone to the power-up state. The power rationing switch may also be actuated momentarily when the telephone goes from the idle to busy condition to initiate a call so as to signal the exchange of the requirement for full operating power. The exchange is capable of deciding whether a telephone wishing to power-up can do so without causing exceeding of an allowable sum of power ration for the telephones of the system. A test center for digitally testing the lines between the exchange and the telephones is also disclosed. The test center causes a digital test signal to be transmitted from the exchange to a telephone at the end of a line under test wherein it is modified in a particular way and transmitted back to the exchange. The returned test signal is compared, at the test center, with a similarly modified non-transmitted test signal enabling a count of the errors to be made. The S/N ratio on the line under test is reduced to increase the errors.

Patent ES-479247-A1 (ES)
Title: Press having overload responsive slide shut height adjusting mechanism
IPC: B30B15/00
Filed: 1979-04-03
Abstract: The reciprocating slide of a mechanically driven press has a ball and socket type interconnection with the connecting rod of the press drive mechanism. The socket component of the interconnection provides a rotatable adjusting screw threadedly interengaged with an annular piston received in a cylinder component on the slide. A locking nut threadedly engages the adjusting screw and is rotatable relative thereto and to the piston to lock the adjusting screw against displacement relative to the piston. During normal press operation the locking nut is biased against a shoulder on the cylinder by hydraulic fluid under pressure in a variable volume chamber between the piston and cylinder components. In response to an overload on the slide, a pressure responsive relief valve releases hydraulic fluid from the chamber and enables relative movement between the piston and cylinder components and thus between the slide and connecting rod.
